A cloaking device, also known as a cloaking system, cloaking shield or invisibility screen, was a form of stealth technology that used selective bending of light (and other forms of energy) to render a starship or other object completely invisible to the electromagnetic spectrum and most sensors. It was encountered in varying forms over the centuries. For a period of time, the Federation considered it the most strategically important Romulan technology. (TOS: "Balance of Terror", "The Enterprise Incident"; TNG: "The Pegasus")
Humanity's earliest-known encounter with cloaking technology came in the year 1986 in the Bering Sea. Admiral James T. Kirk, having traveled back in time, decloaked the Klingon Bird-of-Prey he was commanding to waylay and frighten some whale hunters from killing two humpback whales. (Star Trek IV: Rotta verso la Terra)
One of Humanity's earliest exposures to cloaking technology was in April of 2151, when agents of the approached the starship Enterprise NX-01 undetected and kidnapped a Klingon national named Klaang from the ship's sickbay. The Suliban used cloaking devices on many of their ships, including the , stealth cruisers and salvage ships. The Suliban's cloaking technology had been given to them by their mysterious benefactor from the 28th century. (ENT: "Broken Bow", "Shockwave", "Future Tense")
During a battle near a Suliban helix in a class seven gas giant, Enterprise managed to capture a cell ship. Chief Engineer Charles Tucker III studied the device in his spare time, and in 2152 the ship was used to mount a rescue mission. Unfortunately, Tucker's experience with cloaking technology was somewhat limited and he accidentally doused his hand with the particles the ship used to generate the cloaking effect, temporarily rendering it invisible. (ENT: "Broken Bow", "The Communicator")
Enterprise learned how to penetrate a Suliban cloaking device in March 2152, when the temporal agent explained how to construct a quantum beacon so that Enterprise could reveal the location of the cloaked stealth-cruiser responsible for the destruction of Paraagan II. (ENT: "Shockwave")
Enterprise was also responsible for an encounter with another organization that used stealth technology, the Romulan Star Empire. In April 2152, the ship accidentally entered a cloaked minefield protecting a Romulan-claimed planet. The quantum beacons proved effective against the minefield, but when two Birds-of-Prey suddenly arrived, Enterprise was not able to penetrate their more advanced cloaks. (ENT: "Minefield")
In 2256, the USS Shenzhou encountered a cloaked Klingon vessel. Another cloaked Klingon vessel rammed the USS Europa to demonstrate the technology to the High Council during the Battle of the Binary Stars. (Template:DIS) The Klingon cloak used gravitational bending to conceal the ship from sensors and was a key tactical advantage for the Klingons during the . At the Battle of Pahvo, the USS Discovery devised a method of penetrating the Klingon cloak, destroying the Sarcophagus. This put the two sides on a more even footing once again. (Template:DIS)
In 2266, the USS Enterprise encountered a that used a cloaking device to cross the Romulan Neutral Zone and wipe out several Earth Outpost Stations. The Enterprise was able to defeat the Bird-of-Prey in battle, partially because the cloaked ship was still visible to tracking sensors, but there was no doubt that the Romulans possessed a practical invisibility screen. (TOS: "Balance of Terror")
In 2268, the Federation learned that the Romulans had developed a new and improved cloaking device; one that even tracking sensors could not pick up and that posed a threat to the security of the Federation. On stardate 5027.3, Starfleet Intelligence sent the Enterprise on a covert mission across the Neutral Zone to acquire the new cloak. The mission was a success, and Starfleet was able to procure an intact, modern Romulan cloaking device for study. The Federation also acquired a cloaking device from a captured Klingon Bird-of-Prey, dubbed the "HMS Bounty", in 2286. (TOS: "The Enterprise Incident"; Star Trek IV: Rotta verso la Terra)
By 2269, cloaking devices had further spread within the Klingon Empire as well. One of the first Klingon vessels to be equipped with the device was the IKS Klothos, whose Commander, Kor, used it to great effect at the Battle of Caleb IV. The device was soon used aboard many other Klingon vessels, such as the Bird-of-Prey. At the time Kor acquired the cloaking device, only a handful of engineers in the Imperial Fleet knew how to operate them. (TAS: "The Time Trap"; DS9: "Once More Unto the Breach"; Star Trek III: Alla ricerca di Spock)
In 2311, with the signing of the Treaty of Algeron, the Federation explicitly agreed not to develop or use cloaking technology. The Bajoran Provisional Government also outlawed cloaking devices, stating that the possession of such a device was highly illegal. (TNG: "The Pegasus"; DS9: "Profit and Loss")
In 2370, Quark illegally acquired a small cloaking device that was, as he put it, "not in the best of condition", but it "will work for about fifteen minutes." Initially intending to sell it, Quark instead installed it in the central engine core of a Cardassian shuttle, piloted by Natima Lang, to help the ship escape Deep Space 9 undetected. (DS9: "Profit and Loss")
Following the outbreak of hostilities with the Dominion in late 2370, the Romulan Empire allowed the use of one of their own cloaks aboard the USS Defiant. Although this was originally limited to usage within the Gamma Quadrant, Template:Captain Benjamin Sisko chose to ignore this limitation whenever it was convenient. In order to ensure that the cloak was used correctly, Sub-Commander T'Rul was assigned to the Defiant initially, during the ship's first mission with the cloak. In exchange, Starfleet had to provide all the intelligence it received on the Dominion. (DS9: "The Search, Part I", "The Search, Part II", "Visionary")
Prior to the Cardassians joining the Dominion in 2373, and flushing the Klingons and Maquis out of their territory, the Klingon High Council decided to aid the Maquis in their fight against Cardassia. They provided the Maquis with thirty class-4 cloaking devices with the Klingons' understanding that they were to be used on Maquis ships. (DS9: "Blaze of Glory")
It was even possible for an entire planetary body to be rendered invisible. The planet Aldea was equipped with a powerful cloaking device that allowed itself to fully cloak. (TNG: "When The Bough Breaks")
In order to function, most cloaking devices needed to be tied into a ship's deflector shield grid. (TOS: "The Enterprise Incident") When activated, the cloaking device projects a cloaking field, also known as cloaking shields, around the vessel which selectively bend the path of light and sensors to render the vessel invisible and undetectable. (TOS: "Balance of Terror") The shield can be expanded to cloak multiple vessels. (TNG: "Devil's Due"; VOY: "Tinker Tenor Doctor Spy") However, some models of cloaking device could work without being tied into anything, even having a limited power supply of their own. (DS9: "The Emperor's New Cloak")
Most vessels could not use their weapons and deflector shields when cloaked. Ships of the Klingon Template:Class, for example, were vulnerable to attack for two seconds when their shields automatically dropped as the cloaking field formed. (TNG: "Face of the Enemy"; Star Trek Generazioni) Ships like the Scimitar with more advanced cloaking technology however did not have this problem, as it had primary and secondary shields and weapon systems that could remain online while the ship was cloaked. (Star Trek La nemesi)
Ever since the initial introduction of the cloaking device, there was an ongoing race between the development of new cloaking technologies and the development of new detection systems that could defeat them.
Starfleet's earliest method of penetrating cloaks was developed in 2152, when Daniels provided Enterprise with 31st century quantum beacons so they could locate a Suliban stealth-cruiser. These devices also proved effective against the Romulan cloaking devices used on mines but were ineffective against the Bird-of-Prey cloaking devices. (ENT: "Shockwave", "Minefield")
The cloak used by the Sarcophagus in 2256 used a massive gravitational field to bend light and electromagnetic radiation around the ship, rendering it invisible to sensors. However, imperfections in the field led to near-imperceptible shifts in the background electromagnetic field. Using portable sensor devices surreptitiously planted on the Sarcophagus, Discovery made 133 micro-jumps with the aid of its spore drive, taking readings from multiple vectors in a matter of minutes. Using these readings, Discovery analyzed the correlation between the cloak's field and the background electromagnetic field, allowing the formulation of an algorithm that exposed the enemy ship's position. This ultimately led to the Sarcophagus' destruction. (Template:DIS)
The cloak used by the Romulan Bird-of-Prey that crossed the Neutral Zone in 2266 was less than perfect, allowing a starship to pick up a blip on its motion tracking sensors. This blip was not accurate enough for targeting of weapons and only appeared when the vessel moved, but it was enough to help the Enterprise locate the enemy vessel. By 2268, advances in Romulan technology had removed the problem, forcing Starfleet to steal a model of the new cloak. (TOS: "Balance of Terror", "The Enterprise Incident")
Versions of the cloak used by the Klingons in the late 23rd century also had their flaws. Cloaked Template:Class battle cruisers could be detected using a metaphasic sweep. (VOY: "Prophecy") Energy "distortions", manifesting themselves most often as refracting visible light energy from surrounding stellar objects very near the cloaked ship's outline, appearing as a "shimmering" effect, while cloaked and prior to decloaking, could give away a cloaked ship when observed. (Star Trek III: Alla ricerca di Spock) In 2293, the USS Enterprise-A developed a method of using a photon torpedo to track the plasma exhaust of a cloaked ship. (Star Trek VI: Rotta verso l'ignoto)
